MAKE THE SPREAD: Stir the ingredients together in a bowl.
MAKE THE SANDWICH: Coat each slice of toast with the chipotle spread, to taste. You may have some left over. Divide the chicken between two slices of toast, placing the slices in a single layer on top of the spread. Top with the bacon slices and a single layer of tomato slices. Cover with lettuce leaves and then the remaining slices of toast, spread side down.
Press the tops of the sandwiches down firmly. Using a serrated knife, cut through the sandwiches on the diagonal, then cut through on the diagonal in the opposite direction. Each sandwich will have 4 wedges. Place a toothpick in each of the wedges and serve.
